Yesterday, I finally took closer look at long standing GePeS bug on displaying speed and altitude wrongly (which I've mentioned in very first posts). For some reason I believed it is not my bug, but in QML bindings and let it be there.
Receiving complain from Maarten ter Huurne, that this does not work made me look into it more deeply. Of course I found out it was caused by stupid typo and quickly fixed it. New release is now available on GePeS homepage and will be available shortly in Nokia store.
